I upgraded to Firefox 3.6.12. After doing so I start Firefox and it opens correctly with one tab, showing my home page. When I open a second tab and then try to close the first tab, using the white X in the red box, it will not close. After trying to close the first tab, I close the second tab and instead of closing just the second tab, Firefox web browser shuts down. This happens no matter how many tabs are open after the first tab. I have had as many as 12 tabs open and the first tab will not close.

Reproducible: Always

Steps to Reproduce:
1.Start Firefox
2.Open multiple tab(s)
3.Try to close first tab (It will not close)
4. Close every tab except the first tab, and the last tab closed will shut down Firefox
Actual Results:  
Firefox shuts down

Expected Results:  
Closed the first tab and left the others open. 

Firefox doesn't crash. It shuts down normally when doing the above procedure.
